How to do Calculus I Homework Text: Calculus, Early Transcendentals, 8th Edition Authors: Howard Anton, Irl Bivens, and Stephen Davis Publisher: John Wiley & Sons, Inc. _________________________________________________________________ Read Me 1st : [ UNDER CONSTRUCTION! ] (a) Before you attempt any of the homework problems at the end of a section, it is imperative that you read the section from beginning to end. You should expect to read the section several times. The first reading may be done once over lightly, just to get an overview of the main definitions, theorem, and propositions. In subsequent readings you should dig more deeply into the details. Keep this in mind as you wield your writing utensil on paper: (i) What mathematical objects really are is codified precisely via their definitions. Learn the definitions; (ii) How mathematical varmints behave generally is captured in the magical incantations that follow words like Theorem, Proposition, or Lemma. These may assume a variety of forms and may involve either complex or compound-complex sentences. There is always a hypothesis, which may involve several conditions or properties, and a conclusion, that may also be multipart and involve equation(s), inequalities, or other relations. ; and (iii) The examples that you will encounter in the text come in two flavors: illustrative examples, that reveal how the previous developed theory may be applied in solving a particular type of problem or even suggest how one might further pursue an interesting idea; and counter-examples that show the necessity for particular hypotheses in describing or predicting the general behavior of mathematical varmints. Both types are important. (b) After having read the section at least once, read and work through ALL of the Quick Check Exercises that appear at the beginning of each exercise set. [There is one exception to this. For 11.2 only do QCE's 1 through 3.] You will find a set of "answers" for these exercises immediately at the end of the exercise set, not at the end of the book. Don't peek until you have done them all and don't use a calculator. Take time to write up your solutions with care. The journey is important. Come test time, I do not merely look at what you may claim as your "final answer". [ In fact I discourage "boxing" or "circling" of the end result. ] (c) Once you have completed the Quick Check Exercises, go on to wrestle with a significant chunk of the problems listed by chapter and section in the document Homework Problems. Don't use a calculator. Brief answers to many of the odd numbered problems appear at the back of the book. Essentially all of the problems have an "answer" in the Complete Solutions Manual that may be found online at the Math Department's site at the following URL: http://w3.fiu.edu/math/ To access this document you must have a pdf reader on your computer, say something like Acrobat Reader, or Ghostview, or Xpdf, and you must know an appropriate name and password. [I will discuss the matter on the first day of class and will provide reminders on "class" pages.] Consequently, you may check up on your solutions. (d) When checking answers, keep in mind that there may be alternative, correct solutions, and that things like function identities permit solutions to appear in many different forms. Also, be aware that the answers found in the Complete Solutions Manual are written for instructors. Consequently many are incomplete. As a case in point, the "answers" for the requested proofs involving epsilon antics from Chapter 2 merely provide the key inequalities and do not have the complete incantations required to deal with issues of quantification. Instructors are expected to know how to fill in these lacunae, and by the end of the course you should, too. (e) Finally, some of the problems that have been assigned indicate by means of a small icon that a graphing utility is needed for the problem. This is misleading since, for some, all the graphing utility is intended to supply is a check on a graph that you are to sketch by hand. Here you may use either the answer in the back of the book or the Student Solutions Manual or the Complete Solutions Manual that is online. [Some of the "technology" exercises at the beginning of the text may actually be dealt with by hand later!] (f) In a recent, brief book review by Greg Ross of The Infinite Book: A Short Guide to the Boundless, Timeless, and Endless by John D. Barrow found in the Nanoviews of the September - October 2005 American Scientist is a wonderful quote attributed to John von Neumann. It is this: "In mathematics you don't understand things. You just get used to them." I think this suggests that waiting until two days prior to test time to begin programming your own private biocomputer is singularly unwise. // _________________________________________________________________
